Signal Integrity Analysis
Services:
Designing
a high-speed PCB is becoming more complicated with higher
clock speeds, higher device switching speeds, and higher density.
It is important to analyze signal integrity, SI, before
prototyping. Zebax's Signal Integrity Analysis validates your design
by applying digital and analog signal analysis to help ensure it
will correctly propagate high-speed signals between components and
connectors.
Zebax provides Signal Integrity Analysis with our turnkey
high-speed/high-density designs to help ensure a first-time-right
design.
For Clients who have developed board schematics in-house and just
need specialized expertise from schematic-to-gerber, Zebax provides
services to shorter-term projects.
SI
consists of both pre-layout and post-layout analysis, ensuring
optimal high-speed board layout and material selection. Depending on
the nature of the design and your layout database preferences, we
apply SI tools that integrate with PCB CAD packages such as Allegro,
PADS, and VeriBest.
